SHUTTLE-BINDER.

srncrrionrzon fama m of Letters Patent No. 654,916, dated July 31, leoo. Application filed December 5,1898. Renewed May 31,1900. Serial No. 18,639- (No model.)

To aZZ whom it mayconcern: I

Be it known that I, CHARLES F; PERHAM,

of Lowell, in the countylof {Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Shuttle- Binders, of which the following is a specification.

This invention has relation to shuttle-checking devices or shuttle-binders, as they are usually termed, being designed more particularly as an improvement upon the devices shown in Letters Patent No. 562,653, granted to me June 23, 1896.

The object of the invention is to secure the gradual checking of the shuttle at the end of its pick and prevent it from hanging; andit therefore consists of a shuttle-binder possessing certain features of construction and relative arrangement of parts, all as illustrated upon the accompanying drawings, described in the following specification, and pointed out'in the appended claims.

Reference is to be had to the accompanying drawings, and to the letters'marked thereon, forming apart of this specification, the same letters designating the same parts or features, as the case maybe, Wherever they occur.

Of the drawings, Figure 1 represents in plan View, partially in section, the end of a lay with the shuttle-box. Fig. 2 represents a similar View with the shuttle in the box. Fig. 3 represents in detail a spring.

Referring to the drawings, a indicates the lay, having a shuttle-box bof ordinary con struction.

c is a shuttle-binder which is similar to that shown in myp'iior patent. It is pivoted at c to the shuttle-box, and its free end extends inwardly toward the center of the lay, it being curved, as shown, so that when the free endrests against the outer surface of the shuttle-box its movable portion is projected into the path of the shuttle. Against the end of the binder is a finger cl on the end of a springtensioned dagger-rod 01, such as alsodescrib'ed in my said patent.

The present invention consists of a resilient stripe of suitable material, preferably Wood, which is secured in the shuttle-box to bear against the shuttle. The said strip is rigidly secured by a screw e to'a lug e on the lay in front of the mouth of the sh uttle-box, and it extends through an aperture 6 in the shuttlebox, as shown. The strip is formed with a shoulder a", which bears against one wall of the aperture 6 and with another shoulder a which bears against the opposing wall. The strip decreases in thickness toward its end from theshoulders e e", and it normally lies at an angle across the path of the shuttle, as showiiin FigTl."l have'sfated that I con struct thisstrip of wood, and'the reason therefor is that said material is sufficiently resilient and produces a suitable friction-surface for the shuttle, which is also usually formed of wood, and is durable enough for the purpose for which it is intended.

The supplemental spring 6 andthe part c constitute compound levers for gripping the shuttle with a great pressure, the strip 0 being fulcrnmed near the mouth of the shuttlebox. into the path eitheshgttle, 'yet it is a most parallel with the opposite wall of the shuttle box, so that when the shuttle enters the box its point enters the space between the strip As said, although the strip new and the wall, and its sides are engaged by l the latter as the strip is forced inward by the lever 0. Consequently while heretofore the curved portion at the end of the shuttle struck against the inwardly-extending part of the lever c now it slides between two friction-surfaces which are almost parallel and is easily stopped, whereby I am enabled to run the loom rapidly without breaking the .filling and injuring the shuttle. The strip e may be regarded as a false side wall which tween the strip e and the opposite wall I) of the shuttle-box, said strip having been moved into the'path of the shuttle by said shuttlebinder. The cam or curved edge of the shuttle-binder engages the outer face of the false wall or strip, and consequently as the shuttle continues to enter the box and the binder to move outward the point of contact between said wall and binder advances toward the free end of the said wall, whereby the leverage of the binder against the said wall increases. When the shuttle has been brought to a state of rest, the binder is carriedby its spring back far enough for the false Having thus explained the nature of the invention and describeda way of. constructing and using the same, although without attempting toset forth all of the forms in which. itv maybe made or all of the modes of I its use, I deelare'that what I claim is 1.- A's-huttle-checking mechanisrnieompris ing" a shuttle-box, a false wall attached to the mouth-of the box; and having its free end extending toward-the opposite end of said box,

and ashuttlebinder pivoted adjacentth-e 'last-mentionedend of the said box, said shuttlea binder having an inwardly-curved edge bearing against, the outer face-of the said wall, whereby the point of contact between the-binder and;the wall advances-to- Ward the free end of the-said wall asthe shuttle'continues toenter the box; l

; 2, A shuttle-checking mechanism compris mg a shuttle-box, a shuttle-binder, and a supf plemental resilient, substantially straight "st ip having ne end attached to the mouth opposing wall of the shuttle-box, whereby said shuttle-binder bears against the said free end of the said strip. I v i 3. Ash-uttle -checking mechanism comprisiln-ga shnttle-boxand a substan tiallystraight spring havi-ngone end secured to the shuttle'fbox at themonth thereof, and its free end arranged to be, thrust at anangle to the longitudinal lines of the shuttle-box in the path of the shuttle by the shuttle-binder, whereby said shuttle maybe frictionally engagedsubstantiall-y throughout its whole length by said ing a shuttle-box, having a stationary side 7 wall and a movable false wall between-which the shuttle can enter, said wall being formed of resilient material attached at one end, and a pivoted lever having a cam-surface bearing against said false wall-atits-free 'end whereby said free end may be moved transversely of the path of the shuttle.

' 6. A shuttle-checking mechanism comprising a shuttle-box having a stationary side wall and a movable resilientfalse wall between wall to release the shuttle that it may be pro-. 5 je'cted by the picker-stick through. the. shedwhich the shuttle can enter, said movable wall having one end securedat the mouth f end of the said box, and having its other end ?free to move transversely of the box and a leverfulcrumed near the last-mentioned free end and having acurved surface bearing against said wall, said false wall andilever constituting compound levers for engaging the shuttle.

7. A shuttle=ehecking mechanism comprising a shuttle-box having astati-onary side awall and a movable substantially-straight I false wall between which .thesh'uttle can enter," said movable wall being resilient and having one end secured ator near the mouth of the shuttle-box, with its free end movable transversely of the path of the shuttle and a curved lever fulcrumed near theother end of thebox, and bearing against the saidlmov- .able wall, said wall and'lever constituting compound levers for gripping the" shuttle.

. 8. A shuttle-checking mechanism,eo'mp rising a shuttle-box having a side wall and a H false wall between which the shuttle-can enot the shuttle-box and the other free end projecting between the shuttle-binder and the ter, said false wall being of a length adapted to contact with the shuttlethrou'ghout the length of the straight side thereof, said false wall being attached at one end to the mouth of the box, and having its free end movable transversely of the box, and means eonstructedand arranged to move the freeend of the wallat an angle to the pathof the shuttle, substantially as set forth.

9. A' shuttle-checkingmechanism comprising a sh uttle-box having a falsewall attached to the mouth thereof, with its freeend extending toward the oppositeend of said box, said false wall being of a length adapted to contact with theshuttle throughout the length of the straight side thereof and an automatic binder for moving the free end of the said wall to'an angle relatively to the path of the shuttle to-check-the same and thenreleasing said wall to reduce the pressure of the saidwall against the shuttle.

i In testimony whereof I have afiixed my signature .in presence of two witnesses.
